The Kickstarter campaign for Chris Roberts' new high-end space simulator Star Citizen has proven successful in just one week. At press time, the fund stands at $521,860 from over 11,000 backers, exceeding the project's original $500,000 target.

Star Citizen's Kickstarter fund is actually the game's second crowd-funding source. It follows the donor page at the Roberts Space Industries website, which currently stands at $1.35 million from nearly 15,000 backers. Across both options, Star Citizen has been funded to the tune of $1.87 million of its $2 million total target.

Star Citizen has been in development at Cloud Imperium Games for 12 months. The game itself includes a "sophisticated storyline" that is set in a persistent online universe. According to Roberts, it will fuse elements of his previous games, Wing Commander and Freelancer, and support for the virtual reality headset Oculus Rift is planned.

Much like Guild Wars 2, Star Citizen will be available through a one-time purchase, but will not require a subscription. Players can also purchase virtual items with real-world money to customize their ships.
